Rockford Fosgate power for your sub

Rockford Fosgate performance in a small package. The Prime Series R250X1 mono amp can drive a sub with up to 250 watts RMS, so you can really feel your bass rockin'. You can use the low-pass filter and Rockford Fosgate's famous Punch boost to get the best possible bass from the sub and enclosure in your vehicle. A phase switch gets your subs firing along with your other speakers for maximum impact, while the speaker-level inputs let you hook this amp up to almost any system, even a factory stereo.

Rugged performance and value

The R250X1's heavy cast-aluminum chassis efficiently draws damaging heat away from its internal components, ensuring reliable, long-term play. The amp's built-in sensors keep track of the output current and power supply temperature, ensuring that plunging subwoofer impedances (they change constantly during play) or even a short circuit won't hurt anything. The included wired remote lets you control the amp's volume level from the front seat. Your driver's seat will become your favorite place for listening once this Prime amp goes to work.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Features

CEA 2006 Compliant: The R250X1's power ratings and signal
to noise ratio are measured according to the uniform standards advocated by the
Consumer Electronics Association (CEA). This allows you to accurately compare
these specifications for all CEA 2006-compliant amplifiers, even from different
brands. Manufacturers who adhere to these standards can display the CEA 2006 logo
on their products and packaging. CEA2006 Specifications for this amplifier are:

LED Indicator: The amplifier is equipped with an LED
power/protect indicator. The LED illuminates blue when the unit is turned
on. It illuminates red if the thermal or short circuit protection circuit
is engaged, and the amplifier will automatically turn off.

Mounting: The amplifier can be mounted vertically or
horizontally using the supplied mounting screws. The amplifier should never
be mounted in an engine compartment as this will void the warranty.

Controls

Gain Control: Use the amplifier's gain control to match the
output of the source unit. The rotary gain control is labeled 1 to 11 and has a
sensitivity range of 150mV to 4V when using a preamp level signal, 450mV to 12V
when using a speaker level signal.

Remote Punch Level Control: The R250X1 includes a wired Remote
Punch Level Control, linked to the gain control of the amplifier. The module allows
you to remotely control the output level of the amplifier from the dash or center
console. The Remote Punch Level Control features a rotary dial, and comes with
mounting hardware and an 18' cable.

Note: The Remote Punch Level Control measures
approximately 1-3/4" wide (2-5/8" including the mounting
flange) x 3/4" high x 1-5/8" deep (2-1/8" deep
including the knob and wiring).

Crossover: The amplifier is equipped with a 12dB/octave
Butterworth low-pass crossover. The crossover point is continuously variable
from 50 to 250 Hz. This being a subwoofer amp, the crossover is always engaged.

Phase: The 2-position phase switch allows you to easily
reverse the output phase of the amplifier, choose 0° or 180° to match the
rest of your vehicle's speaker system.

Punch EQ: The Punch EQ bass boost circuit is adjustable from
0 (min) to +12dB (max) and centered at 45Hz.

Connections

Power Terminals: The power and ground terminals are nickel-plated
set screw terminals and will accommodate up to 4 gauge power and ground wires.

Fuse: An external 30-amp fuse (not
included) must be installed on the power wire at the
battery. If a wiring kit is used which includes a fuse
with a value other than 30-amps, the original should be
replaced with a 30-amp fuse.

Remote Turn-On Terminal: The remote turn-on terminal is a
nickel-plated set screw terminal that will accommodate up to an 8 AWG wire. It's
used to remotely turn the amplifier on and off.

Speaker Terminals: The one pair of speaker outputs is
nickel-plated set screw terminals what will accommodate up to 8 AWG speaker
wire.

Speaker Level Input: A speaker level input harness is
included, making it easier to add the amplifier to a factory radio or to a
receiver with no preamp outputs.

RCA Output Jacks: A pair of RCA pass-thru jacks provides a
convenient source for daisy-chaining an additional amplifier without running an
extra set of RCA cables from the front of your vehicle to the amplifier location.

Wired Remote: An RJ-25 jack is used with the included Remote
Punch Level Control.

very nice amp

This is my first install of any amp. I think I choose wisely! If I had the extra money, I woulda went 4ohm mono at 250rms or more, but that gets expensive. Running at 2 ohms loud, it starts to get hot sooner than later. But good bang for the dollar! Highly recommended.

Pros:Nice and small, Allen wrench on every terminal! Loved that. Made it easier for me. No matter how ya mount it, easy access to adjustments.

Lots of juice!

I've never have a small amp that said that it was 250 watts actually do it. I tested this amp and it was putting out 345 watts. I've got it running a single Rockford Fosgate P1 10inch sub in a ported box and it gets loud. I've had others ask me if its 2 12 inch subs.

Pros:Puts out more power than stated, very compact size, easy installation, looks good
